Daniel Mühlbachler became interested in Computer Science shortly after starting high school, where he was later developing web applications as part of the scholarship program for outstanding pupils.

Besides having a profound knowledge of web development, such as PHP, HTML, and CSS, he has also worked with a variety of other programming languages, such as Java, Groovy/Grails, Objective-C, MATLAB, and C, and is skilled in Linux server administration. For his Bachelor's thesis at Johannes Kepler University in Linz, Austria, he worked on aerosol satellite data processing for mobile visualization, where he also got familiar with MongoDB and processing big amounts of data.

He enjoys solving challenging problems and is always keen to work with new technologies, especially with Big Data, functional programming, optimization, and NoSQL database-related ones.
